Reproductive Costs In Female, Island-Dwelling Eastern Diamondback Rattlesnakes (Crotalus Adamanteus), Emily R. Gray 2025 Marshall University

Reproductive Costs In Female, Island-Dwelling Eastern Diamondback Rattlesnakes (Crotalus Adamanteus), Emily R. Gray

Theses, Dissertations and Capstones

Eastern Diamondback Rattlesnakes (Crotalus adamanteus; EDBs) are a declining species endemic to the Southeastern Coastal Plain. Reproduction is costly for females, which are ovoviviparous, slow to mature, reproduce infrequently, and are often emaciated after parturition. Yet, we have a limited understanding of the trade-offs associated with their reproductive biology. Thus, I had three objectives: 1) assess reproduction-associated water stress and determine how female EDBs respond to altered water budgets in situ (Chapter 1), 2) evaluate the interactive effects of body condition and rainfall on female hydration, with a special focus on musculature as a condition index (Chapter 1), …

Spatial Analysis Of Heavy Metal Enrichment In A Historic Appalachian Mining Stream, Eric M. Torres 2025 University of Mary Washington

Spatial Analysis Of Heavy Metal Enrichment In A Historic Appalachian Mining Stream, Eric M. Torres

Research and Creativity Symposium

This study examined the spatial distribution of heavy metals along the Levisa Fork and primary tributaries in Buchanan County, VA and Pike County, KY. Buchanan and Pike Counties have a long history of coal mining, a process known to release heavy metals into surrounding waterways. Exposure to certain heavy metals, such as arsenic and lead, has been known to cause health problems, such as cancer and organ damage. The study looked at concentrations in riverine sediments, surface water and groundwater for As, Al, Cr, Cu, Fe, Li, Mg, Mn, Ni, Pb and Zn. Sediment samples were collected, dried and digested …

Nitrogen Sufficiency Index (NSI) is an important nitrogen (N) stress indicator for precision N management. It is usually calculated using variables such as leaf chlorophyll meter readings (SPAD) and vegetation indices (VIs). However, no consensus has been reached on the most preferred variable. Additionally, conventional NSI (NSIuni) calculation assumes N being the sole yield-limiting factor, neglecting other factors such as soil water variability. To tackle these issues, this study compared various variables for NSI calculation and evaluated two new N stress indicators in minimizing the impact of confounding water treatment. The following ground- and aerial-derived variables were compared …

A Metadata Analysis Of Unionid Mussels Of The Greenup Pool Of The Ohio River Using Occupancy Modeling And Species Area Curves, Tyler Mitchell Annarino 2025 Marshall University

A Metadata Analysis Of Unionid Mussels Of The Greenup Pool Of The Ohio River Using Occupancy Modeling And Species Area Curves, Tyler Mitchell Annarino

Theses, Dissertations and Capstones

Although North America contains the largest diversity of freshwater mussels in the world, only ~24% of species in the United States and Canada have stable populations. This group provides unique hurdles for surveying, and current unionid survey protocols include neither longitudinal studies nor randomization of sites. This project conducts a metadata analysis of freshwater mussels in the Greenup Pool of the Ohio River (GPOR) to answer three questions: 1. Does a combination of longitudinal scope, randomization of sites, and historic methodology of surveying result in useful occupancy/detection models (ODMs) of unionids in large streams at the family level? 2. Does …

Ecological restoration is essential for improving the ecological integrity of degraded ecosystems to enhance ecosystem services and biodiversity. In this study, we assessed the effectiveness of wetland restoration on retired cranberry farms by analyzing vegetation recovery and surface-water dynamics using the enhanced vegetation index (EVI) and normalized difference water index (NDWI) derived from Sentinel-2 satellite imagery. To quantify temporal dynamics of both vegetation recovery and surface-water cover, we identified the spectral distinctions among restored wetland plant communities. Our results indicated the emergence of distinct plant communities upon restoration. Restored wetlands in general showed significant and progressive vegetation recovery and expanding …


Effects Of In-Stream Large Woody Debris Management On Riparian Salamander Population Dynamics, Sydney Hermann 2025 Marshall University

Effects Of In-Stream Large Woody Debris Management On Riparian Salamander Population Dynamics, Sydney Hermann

Theses, Dissertations and Capstones

The addition of large woody debris (LWD) into streams is an increasingly common habitat restoration method used to support brook trout populations and other sensitive freshwater species. Wood jams create localized reductions of water velocity, increase organic matter retention, intensify overbank flows, and promote habitat heterogeneity. These changes enhance interaction between the floodplain and the stream which can influence forest habitat variables such as leaf litter, soil pH, moisture, and invertebrate abundance. Salamander demographics reflect the stability of these forest habitat variables, and population declines can be indicative of environmental disturbance, stress, or change. Evaluating how this trout-targeted management effects …

Citizen’S Rare Plant Watch, Nora Dunkirk, Gabriel Campbell, Kris Freitag

Rae Selling Berry Seed Bank and Plant Conservation Program

Rare species data for plants is lacking, hindering land management decisions and conservation outcomes. With Citizen's Rare Plant Watch, we empower citizen scientists to provide the “eyes on the ground” and collect data needed for conservation decision making in Oregon.
